Studies on the Structure Model of Coal and Its Polarization Characteristics

The macromolecular structures of coal samples collected from Yutianbao, Nantong and Qingnian coal mines in Sichuan were studied and a model of structure for these coals was set up. On the basis of above mentioned work,experimental studies and theoretical analyses were made to investigate the characteristics of coal polarization in applied electric field. The results indicate that the rotation polarzation and the space polarization are the essential reason for the attenuation of electric current through coal samples,and that the space polarization is the main form of coal polarization.
